CUDA 5.5 is the first version of the parallel computing platform and programming language to play nice with ARM, meaning it natively supports GPU-accelerated computing on systems built around ARM chips. It will also make it easier and faster for developers to port applications over.
Other than ARM support, CUDA 5.5 brings a handful of other upgrades to the table, including enhanced
- Hyper-Q support for multiple MPI processors via the new Multi-Process Service (MPS) on Linux systems
- MPI Workload Prioritization enabled by CUDA stream prioritization
- Multi-process MPI debugging & profiling
- Single GPU debugging for Linux
- Static CUDA runtime library
- RPM/DEB packaging & new NVIDIA repo
